I think it is one thing to ask who are your top 10 favorite Saints, it is another to ask WHO are the the top 10 greatest saints, be careful in making such judgement.
From one of my favorite books.
"The man who thinks of the greatness of his own sins and the littleness of his virtues, and of the distance between himself and the perfection of the saints, acts much more acceptably to God than the one who argues about who is greater or who is less. It is better to invoke the saints with devout prayers and tears, and with a humble mind to beg their glorious aid, than to search with vain inquisitiveness into their secrets."
"Many ask who is the greater in the kingdom of heaven when they do not know whether they themselves shall be worthy of being numbered among
its least. It is a great thing to be even the least in heaven where all are great because all shall be called, and shall be, the children of God. The least shall be as a thousand, and the sinner of a hundred years shall die. For when the disciples asked who should be greater in the kingdom of heaven they heard this response: "Unless you be converted and become as little children, you shall not enter into the kingdom of heaven. Therefore, whosoever shall humble himself as this little child, he is the greater in the kingdom of heaven." The Imitation of Christ, Chapter 58, High Matters and the Hidden Judgments of God Are Not to Be Scrutinized
